Določanje popustnih karakteristik orodnega jekla D2 : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programJakše, JakobEksperimentalna raziskava zajema vpliv spreminjanja medija gašenja, temperatur popuščanja in števila ciklov popuščanja na orodno jeklo za delo v hladnem D2. Namen raziskave je bila ugotovitev ... optimalnih parametrov toplotne obdelave za dosego želene trdote materiala s hkratnim ozirom na nekatere ostale mehanske lastnosti jekla. V eksperimentalnem delu smo pripravili serijo vzorcev orodnega jekla D2, ki smo jih kalili z dvema različnima medijema gašenja in nato večkrat popuščali na različno visokih temperaturah. Po vsakem koraku toplotne obdelave smo vzorcem pomerili trdoto z metodo Rockwell C. Na koncu toplotne obdelave smo vzorcem izmerili tudi zaostale napetosti po metodi rentgenske difrakcije ter pod optičnim mikroskopom analizirali razlike v mikrostrukturi. Ugotovili smo, da je optimalna temperatura popuščanja 550 °C, saj trdota jekla pri popuščanju na višjih temperaturah pade, njegove mehanske lastnosti pa bodo pri nadaljnji uporabi do delovnih temperatur 550 °C odporne na spremembe.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
